OIL-CAKE PAN.

To all whom it may concern" Be it known that I, ALFRED W. FRENCH, acitizen of the United States, residing at Piqua, in the county of Miamiand State of Ohio, have invented a new and useful Improvement inOil-Cake Pans, of which the following is a specification.

This invention relates to improvements in cake pans which are used inoil expressing mills for carrying the oil cakes from the cake former andinserting them into the boxes or spaces between the horizontal plates ofthe oil press. These cake pans, as generally made, consist simply of afiat rectangular piece of sheet steel with a handle at one end. They areusually made of about sixteen gage steel and weigh about ten to twelvepounds. The pan shover slips the pan under I the molded cake in the cakeformer and shoves the pan with the cake thereon into the press box, orspace between adjacent plates of the press, and withdraws the panleaving the cake, which is wrapped in the press cloth, in the press. Asthe pan has a smooth surface the cake is apt to slide back on the panwhen inserting it into the press box, if it fits closely in the box, andthe pan shover has considerable difficulty at times in inserting thecakes. Furthermore, the pan shover has to work rapidly to remove thecakes from the cake former as fast as they are made, and in fillingpress boxes which are open at both the front and rear ends, he is liableto push some of the cakes into the boxes too far or not far enough, sothat when the pressure is applied the cakes will project beyond the endsof the boxes, which leaves the cakes with soft end portions from whichthe oil is not fully expressed. The press cloth is simply wrapped oncearound the cake with its ends overlapping, as shown in the drawings, andin inserting the cakes into the press the cloth is frequently pulledback away from that end of the cake which is last to enter the press,which also results in this portion of the cake being left soft or notproperly compressed.

The object of this invention is to produce a practical and desirablecake pan which will enable the cakes to be rapidly placed in properposit-ion in the press boxes without especial care on the part of thepan shover and which will prevent the cloths from being pulled back awayfrom the ends of the cakes, thereby overcoming the above Specificationof Letters Patent.

noted objections to the cake pans heretofore used; and also to provide acake pan of simple and inexpensive construction which is much lighterthan the old style pans, so as thereby to materially lessen the labor ofthe pan shover. These results are accomplished by providing the cakepanwith a back stop which engages the cake and positively shovesitinto thepressbox, and also with a stop which engages the press and limits themovement of the pan into the box, thereby serving as a gage to insurethe correct positioning of the cake in the box. The pan is also providedwith movable fingers for holding the press cloth firmly against the cakeand preventing it from be ing rumpled or pulled away from the cake wheninserting the cake into the press. Instead of making the pan of aplain-faced steel sheet stiff enough to retain its shape, it ispreferably made of a corrugated thin sheet which is very much lighterand therefore greatly reduces the weight of the pan.

In the accompanying drawing, consisting of two sheets: Figure 1 is afragmentary sectional elevation of an oil press illustrating the use ofa cake pan embodying the invention. Fig. 2 is an enlarged fragmentarysectional elevation of the pan holding a cake. Fig. 3 is a reduced planview of the pan.

.Fig. 4 is a side elevation thereof. Fig. 5 is an enlarged sectionalelevation through the handle of the pan.

Like reference characters refer to like parts in the several figures.

The body, A, of the pan is of rectangular shape and of substantially theusual dimensions, but instead of being a plainfaced sheet of steel ofthe thickness necessary to prevent it from bending in use, it ispreferably made of a thin light sheet of steel, or other suitablematerial, which is corrugated longitudinally, as shown in Fig. 3, toafford the necessary stiffness or rigidity.

Near the handle end thereof, the pan is provided with an upwardlyprojecting back 7 7 body.

ward movement of the pan. As shown in the drawings, the back stop B andthe stops C are formed respectively by an upwardly bent and twodownwardly bent integral portions of the pan body, the former beinglocated between the latter. Manifestly, however, the pan could beprovided with one or more upwardly projecting parts formed thereon orsecured thereto in any suitable way for engaging the cake and with oneor more stops formed thereon or secured thereto in any suitable way forengaging a suitable part of the press to properly limit the movement ofthe pan into the press.

D represents the handle of the pan which, as usual, is located at oneend of 'the pan, and E E represent fingers or parts which extendforwardly from the handle over the pan so as to bear on the adjacent endportion of the cloth-covered cake. The handle is mounted to rock or turnfor raising the fingers to enable the pan to be shoved under the cake inthe cake former, and is actuated by a spring F which presses the fingersagainst the wrapped cake so that the cake is grasped firmly between thefingers and the body of the pan.

The handle preferably consists of a tube loosely surrounding a rod ortube cl which extends across the end of the pan body and is riveted orotherwise rigidly secured at its ends to the opposite side portions ofthe pan The spring F surrounds the rod or tube (2 inside of the handleand is attached in any suitable manner at one end to the handle and atthe other end to the rod or tube (i so that it acts to turn the handleand press the fingers E toward the body of the pan. The handle can beconstructed and rotatably connected to the pan in any other suitable wayand any other sort of operating spring for the holding fingers can beused.

In using this cake pan, the pan shover slips the pan under thecloth-covered cake in the cake former box at the same time turning thehandle D by a twisting motion of his wrist so as to allow the cake toenter beneath the fingers E. When the cake is in position on the panwith its end against the back stop B, he releases the handlesufficiently for the spring F to press the fingers E firmly down on thewrapped cake. The

pan is then withdrawn with the cakefrom the former and shoved into thebox or space between plates of the press until the pan is arrested byits stops C striking the press rack, which, as explained, properlylocates of the cake and effectually prevent the cloth from being rumpledor pulled away from the cake by frictional contact with the press box orplate when inserting the cake.

By corrugating the pan as explained, a very much lighter sheet steel canbe used which greatly reduces the total Weight of the pan. Theimportance of this will be realized when it is considered that the panshover frequently carries the pan with its cake between the cake formerand the press three thousand or more times in a day.
